holy shit... I came here to get some more FAQ's to see some more knowledge about KA-T's but all I see are these dumbass questions.

FAIL.

Well..... The stock maf will not take you very far....the FMU will only do so much, you're going to need larger injectors. T3 turbo, so most likely it is externally wastegated, so you'll need one of those. ARP hardware is good insurance.

For starters.

Definately gunna need at least SR injectors. And the stock RB20 turbo is just a t3 flanged t25 w/ an internal wastegate so he wont need that. And I would definately recomend ARP hardware =)

Thanks for the correction, i wasn't aware of the t3 flange t2 turbo for the RB. Don't want to give out misinformation!
Then yes at least sr injectors would be good.

Is there no moderator for this thread? It's a shame all the usefull info in this thread is impossible to find among all of this other garbage. I think this thread should no longer be classified as a FAQ STICKY.

[1sttime240driver]

Im new to this website and forum so im not sure if im posting in the right place so please excuse my mistake.

I have and '89 240sx with the ka motor. I just bought it 3 days ago and it makes this pinging noise when i accelerate. I had to get on the interstate to get to work this morning and when i got up to about 65 mph it wouldnt go any faster and the more throttle i gave it the more power i would lose. The car threw some pretty thick white smoke out the exhaust and died. Now when i turn it over all it does is whine.. It sounds like its not turning the cam or the valves but im not sure. Im not very familiar with imports but im learning. Could it be the timing chain? And if so what else gets damaged when that happens? Bent valves?

Please HELP!!!

[1sttime240driver]

I think my timing chain snapped. How would i know that for sure? What would it sound like? And what else is damaged when that happens? Please HELP!!!

Re-check that both of your cam sprocket and crank sproket are set to TDC (NEVER turn them independently, always with the chain on) make sure that your marks on the oil pump and the oil pump rod (it connects to the crank spindle and distributor) are lined up the check your distributor is lining up with the oil pump rod. This is very easy there is a thread on this somewher here that links to another forum just SEARCH.

First and foremost that motor is toast!!! Why didnt you check for compression and oil level when you bought it? These are old cars which arent always taken care of. Secondly..........

WTF!!!!! do you people not understand about this being a KADET thread! AGAIN got to the tech forums and ask away or do some searching on your own.

Just read the first page. it covers everything you need to know. just to cover the basics... Z32 tuned MAF, TURBO AND INJECTORS DEPENDS ON THE HP, tons of manifold options, just dont trust ebay too much, if its not a walbro you'll probably kill your fuel pump in no time from starving it. if going for big power such as 300+ your gonna want to do the rods, pistons, new gaskets, bearings, clean your block to perfection, and make sure you can put it back together if you take it apart. if you already have running car i would work on its handling before getting into the power issues. Anyways just go to the first page of this thread. but also before you post again read the new members thread so you dont embarass yourself.

[M4J0R T0M]

Alright guys, need a little advice here. I'm building a KA-t and I've nearly got all my parts together, just have a couple questions about the rest of what I need. I'm going for a mild (low-mid 200's) build using mostly stock SR parts. I'm on a pretty tight budget also so keep that in mind.

Here's what I have so far:
XS Power tubular bottom mount
Fresh T25
XS Power elbow
Blitz 3" dp
2.5" custom exhaust, I know 3' would be better but this one was basically free
24x12x3 eBay FMIC with a bunch of misc piping
stock maf
Apexi AFC Neo
SR 370's
Exedy stage 1 clutch


Things I still need:
Wideband -- What do you guys suggest? LC-1?
Turbo oil and coolant lines -- Where's the best place to get them and how to mount them? I know I have to weld a bung in the pan, but what about coolant supply and drain and oil feed.
Gaskets and studs, will autozone parts be ok for this?
BOV, thinking about getting a cheapy eBay bov.
Walbro pump - probably just get it on ebay.
Would I benefit at all from getting a SR maf? Will it support any more hp than my stock S14 maf?

I'm going to be running all this on a stock KA with about 165k on the clock. It's got good compression across the board and it feels pretty strong and healthy. I want to keep it that way, so I'm gonna keep it under 300whp until I can afford the AMS rebuild kit. Then I'll probably step up to a T3 and turn up the boost.

[n8RPS13]

Finally someone with a LEGIT KA-T question! LLooks like you are well on your way man! As far as the oil and coolant lines its best to have a legitimate shop to weld in your oil pan line and as far as the rest thats just up to you as far as your setup goes. Sorry I dont really have a good answer for that. You should definately pull your head and replace the head gasket with a Cometic and use ARP head studs and while you are in there might as well replace the timing chain, get a complete kit sprockets and all. I believe cimotorsports.net has some decentely priced timing kits. EGay BOV will work as well. If your going to change the MAF might as well step up to Z32 or Q45 maybe even a Cobra. JWT has a lot of helpful info on their site as well. Im using a lot of their stuff and suggestions as they have been in the Nissan game for awhile! GL man!

[Walperstyle]

^you don't need a Cometic head gasket. Many guys with high horsepower are running a Felpro. I will be too my first few times.

Reason: If your head and block have been decked and mirrored to each other, then it doesn't matter what you have; so save the money if you can.

ECU tune is most important, and for everyone doing any type of performance, Get a good wideband o2, and stand alone like AEM, Motec, Vipec, Haltec. Sure it costs, but at least you know everything going on in your engine.

Also, if you have the resources, change over to a MAP sensor instead of MAF. Maf's are kinda stupid at the best of times. I would also never trust my engine to an Unknown Ebay BOV or external Wastegate. Thats just me.

[-LSD-]

Have a little question.
Im almost done with my turbo kit.
this is what i have so far

built ka with 2k miles on it
Oem head gasket
ARP hardwear
Emance ecu (all the rumors...what do you think?)
550s (power enterprise)
z32 maf
t25 turbo (will be water cooled) shooting for 10 psi
JGS oil lines
XS power boost controller with 2 settings.
and asome random stuff

ok what im missing is manifold..i was looking at isis version 2 if im not mistaking...its 200 bucks and seems like people pretty happy with it.
Intercooler, ill run whatever ill find cheap, not planning to run BOV, didnt have it on my previous sr's, everything seems to be fine, what do you think?
FPR...what will you recomend for decent price? im a student = broke as fuck
Also previous owner claims that there is walbro 255 on the car...idk, cant trust anyone. is there a way to tell walbro from stock? or should i just buy new one and sell the one i have right now?
I will be using stock sr elbow and downpipe, ive heard there shouldnt be any problems with that, i would love to confirm it...any1 using this setup?
Want to discuss OEM headgasket...ive been talking to people who into drag racing, who building high boost (mostly honda engines), they all use oem headgaskets, they saying if anything goes wrong and there is detonation or preignition hg will act as a blow of valve and will let access pressure into coolant, that way its gonna save the motor from rebuilt, but hg wearing out pretty fast. Im not planning to go over 300hp, but i still preferred extra protection, whats your opinion? what do you use?

Also im very curious about blow through set up, it looks like thats what i will be doing, previous owner of the ecu said he was using blow through and didnt have any problems, i was trying to find any info on it...some people saying its good, some people saying its dumb...but ive seeing a lot of people using them on ka-t. I want to hear your thoughts and opinion on this.

thanks for your suggestions in advance.

p.s. looks like this thread is dying, thats very sad...we need more ka-t in 240 community

[steezywonders]

i was wondering if anyone know if ka24et/ka24det are smog legal in california???

[JuniorsSr]

I have s14 turbo/manifold/370 injectors/ front mount/piping/255 walbro/z32 mafs still need safc/2 this is for kade I'm only planning on 230-250 rwhp do I need to change head gasket or will it hold up? Thanks

[venom2034]

once everything is said and done and i have my awesome ka-t setup put together, what are some basic guide lines for tuning the motor. how do i go about this? i cant really find good info on steps to tuning the car. I find plenty on the components but when it comes to tuning there isint much.

[NoPistons!]

KA-T.org - The Home of 1000+ whp/7 sec Turbo KA's.


Depends on what you are tuning with. PFC, MSNS, AEM, EMU, MOTEC, ROM, Seat of your pants safc/wideband....etc......
